LAMP-HOLDER Application filed May 3,

To alt whom t may concern.'

Be it known that I, WILLIAM J. Fnlsnin, a citizen of the United States, and a resident of Chicago, in the county of Cook, State of Illinois, have invented certain new and useful Improvements in Lamp-Holders, of which. the following is a specification.

My invention relates to lamp holders, particularly to holders which can be conveniently and detachably stuck or driven. into cracks, crevices or soft material to form a support and which is provided with means i for adjustably supporting miners acetylene lamps thereon.

Miners frequently iind it desirable to support their cap lamps from a wall, post or other structure in mines. rlhere are devices of this class in the prior art, but they are all more or less impractical, unreliable and expensive to manufacture, and do not efficiently support lamps. Among the important objects of my invention are: to provide a holder in the form of a pin which can be readily stuck into cracks or soft material. and driven into harder material; to provide an improved frame detachably applicable to said pin into which a lamp can be readily inserted to be securely held to the pin; to provide an arrangement which will cause the frame to become automatically locked to the pin when the lamp is inserted; to provide an arrangement which will permit free rotational movement of the lamp while being securely held on the pin; to provide an arrangementwhich will permit the pin to serve asia carrying handle `for the lamp when the pin is detached from its support; to provide a pin with a wedge shaped insertion end and means for permitting application ofthe supporting frame to the pin so that the lamp canbe supported on any side of the pin; to provide a supporting frame which can be constructed from a single piece of wire; and in general to provide `a supporting structure of the class referred to which is simple, strong and efficient and `which can be inexpensively manufactured The above and other features of my invention are incorporated inthe structure shown on the accompanying drawing, in which drawing- Figure l is a side elevational view of the holder applied to a supporting wall and having a lamp mounted thereon,

Fig. 2 is a plan view of the holder with the lamp removed,

Fig. 3 is a sectional view on plane 3-3, Fig. l,

Fig. l is an enlarged sectional view on plane 4 4, Fig. l,

Fig. 5 is a similar sectional view showing a modilied locking arrangement and j Fig. 6 is also a similar sectional view showing another modified form of locking arrangement for the frame on the pin.

The pin l) 1s formed on a single length of preferably steel bar of polygonal cross section, the pinshown being of rectangular cross section. One end of the pin is forged or otherwise formed down to form a sharp wedge-shaped end l0, while the other end of the pin is bent to 'form the circular head ll. Intermediate its ends the pin has a number of holes l2 and l2 drilled theretlnfough and extending alternately in opposite direction at right angles with the opposite side of the pin. 'lhe lamp supporting frame F is bent up from a single piece of wire tempered tothe suitable springiness. The fra-me has the middle or 'upright section iii-and the upper horizontal, section 14, this upper section being bent to forni an open ring of approximately 270 degress e.\ tent, the end l5 being bent out slightly and the bend 1G vbeing' rounded so that a lamp can readily be inserted into the ring bctween the end and the bend, the diameter of the ring being such as to readily receive a miners lamp L around its cylindrical waist 17, as clearly shown in Fig. l, the ring being normally slightly contracted so that when the lamp applied, it will be clamped by the'ring but will, be free to be rotated therein under slight 'torce applied to the lamp.

At its lower end, the wire frame is bent laterally in the direction of the open end of the ring 1 4-, to form the side loop 18, and beyond this side loop the wire is bent horizontally in` the opposite direction to form the section 1S), then inwardly in the direction of the ring and slightly inclined downwardly to form the section 20, and then laterally in the direction of the open end of the ring to form the horizontal end section 21. This end 2l is inserted through one of the horizontally extending openings l2, and the section 19 is brought against the topof the pin, the section 20 beimT sniiiciently slanted so that when in this position y thel ring 14 of the frame will be horizontal.

When the lamp is now inserted into the ring it will seatA on top of the pin, and the distance between the pin and the ring is such that the frame will be strained sufficiently when the lamp is inserted to exert slight downward pressure which serves to hold the lamp rigidly against the pin to prevent rattling thereof. The lamp is however free to be rotated into any position on the pin by a slight rotative effort thereon and the clamping engagement of the frame on the lamp and between the frame and pin will hold the lamp in any position to which it has rotated. rl`he upper part'13 of the upright section 13 is slightly inclined or bent so that the frame will be cleared by the reflector R of the lamp which will enable the lamp to be turned entirely around without ever striking the frame. The wire frame can be first applied to the lamp and then both the frame and the lamp applied tothe pin, or,`the wire frame can first be applied to the pin and the lamp then forced into the ring 14.

Ordinarily, the clamping engagement of the frame with the lamp will hold the lamp to the pin, but miners are more or less rough in handling devices of this kind so that l preferably provide means for locking the frame to the pinv to prevent accidental disconnection. One arrangement for locking the frame is shown in Fig. 4L. Here1 the lower limb of the loop 18 is deflected flownwardly a distance to form the bead or rounded ridge 22 which, when the wire frame .is applied, engages with the. side of the pin opposite to the side from which the end 21 isV inserted through the pin. Then the lamp is applied in the supporting frame, engagement of the bead with the pin will be maintained and the wire frame is securely locked against accidental displacement. The bead is however made sufficiently short and gradual that under exertion of lateral pressure against the frame it will spring sufiiciently to permit removal of the frame Vbefore the lamp is removed therefrom and likewise, to permit the frame and lamp to be simultaneously applied to the pinv The bead will however, insure against accidental displacement of the wire frame after application.

In Fig. 5 an arrangement is shown with which the wire frame must be applied first to the pin and the lamp inserted afterward. `Here the loop 18 has the more pronounced 'extension 23 which has extended engagement with the side of the pin. With this arrangement the lamp must be removed Y from the frame before the frame can be rGifs withdrawn from the pin.

InYFig. 6 still another locking arrangement is shown. Here, the end of section 21 s threaded to receive a nut 2land with this arrangement, like with the, arrangement in Fig. 5, the frame must be applied to the pin before the lamp is applied, and the lamp must be withdrawn from the frame before the frame can be released from the pin.

rlhe circular head ll affords a convenient means for carrying the holder and lamp when the holder is withdrawn from a support, and when the pin has been fastened to a support, this circular ring also serves as a support on which things can be hung.

rlfhe pin is usually applied by inserting its fiat wedge-shaped end info a crack, or by driving it into softer material such as wood, coal or earth. Sometimes horizontal cracks or fissures are available but other times only vertical fissures or cracks are available and it is for this reason that l extend some of the holes 12 in one direction through the pin and other holes l2 in directions at right angles. The pin can be readily aceonnnodated for application in availabe cracks by inserting the frame into one or another of thI available holes through the pin. As the pin is of steel it possesses great strength and can be driven into a support to be securely held. frs the entrance ends of the ring ll are well rounded and round wire is preferably used for the frame, the lamp which is usually constructed of softer material such as brass, will not be injured during application to the frame or during` adjustable rotation on the holder.

l thus provide a very simple, strong and eHicient holder structure. 'lhe pin can be inexpensively bent up from a single length of stock material and likewise the holder frame can be inexpensively formed from a` single piece of wire. l do not, of course, desire to be limited to the exact construction, arrangement and operation shown and described as modifications are possible which would all come within the scope of my invention.

I claim as follows:

l. ln a lamp holder of the class described, the combination of a pin having a hole therein, a frame having a laterally extending end section and a laterally ex tending intermediate section for engaging respectiwly in said hole and on said pin, the upper end of said frame being formed to span a lamp at an intermediate part thereof to thereby hold said lamp on said pin.
